    摘要: An apparatus for Flash X-ray irradiation of material includes a Flash X-ray source comprised of an electron gun and an anode. The electron gun comprises a field emission cold cathode having an electron emitting surface, and a grid for controlling electron flow from the cathode to the anode. The anode has an electron-receiving main surface and an X-ray emitting, oppositely facing main surface. The X-ray emitting surface, emits X-radiation into an irradiation volume. The X-ray emitting surface of the anode has orthogonally oriented first and second dimensions of greater than 2 millimeters each. A high voltage pulse power supply powers the Flash X-ray source. The electron gun, anode and high voltage pulse power supply are so constructed as to create sufficient X-radiation in said irradiation volume to achieve a desired level of irradiation of material in said volume.

    摘要: A mobile X-ray apparatus (20) is disclosed which incorporates a power supply (22) in which the energy for operation of the X-ray tube (21) is supplied from a flywheel (50) coupled to an electrical machine (24) which functions as both a motor and generator. In the motor mode of operation, a controller (21) provides power to the machine (24) to operate it as a motor and drive the flywheel up to a desired operating speed. Upon request of the operator to initiate an exposure, the controller power is disconnected from the machine and the power terminals (32) of the machine (24) are connected to a transformer and rectifier (27) which increases the generated voltage and rectifies it to provide the high voltage across the X-ray tube (21) required for proper exposures. The controller (31) provides a first selected level of current to the control winding (77) of the machine (24) required during the motor mode for proper motor operation, and provides a higher selected current level to the control winding (77 ) during generator operation. The controller also provides a boost in the control winding current as the machine (24) begins to supply power during an exposure to compensate for the voltage sag that ordinarily occurs upon loading of the machine to thereby maintain the output voltage substantially constant.

    摘要: A portable X-ray source device for producing a selected number of uniform X-ray output pulses. The device comprises a spiral capacitor voltage generator, a transformer assembly and a coldcathode emitter X-ray tube. The capacitor and transformer are coaxially disposed in mating sections of a cylindrical canister which is evacuated and filled with oil. The tube is disposed centrally within the capacitor and transformer for packaging efficiency. Corona suppression means are provided for preventing high voltage damage within the canister. The X-ray tube employs an emitter comprising spaced rings of woven graphite material. A spark gap trigger device including tungsten electrode strips is mounted on the outside of the canister where it can occupy the corner space of a square sheet metal housing. A slide-in battery cartridge and high power converter circuit are provided for dc operation.
